Its ability to electronically steer and focus ultrasonic beams allows for comprehensive inspections with improved accuracy. However, the performances of an ultrasonic inspection may be degraded when the component being inspected exhibits an uneven surface. If the surface geometry is unknown, phased array technology is unable to correct the perturbations of acoustical beams using array settings. In this work, we present a new immersion adaptive inspection technique of large and complex-shaped components using a matrix array. In this approach, first, the unknown surface geometry of the inspected component is reconstructed from a series of 2D TFM images collected using only one row and one column of the matrix array acting as two independent orthogonal 1D arrays, in conjunction with mechanical 2D scanning. At this stage, the recorded 2D images are combined into a single wide-view 3D surface image by rotational SAFT algorithm, a simplified version of the standard SAFT method. The desired surface is extracted from the resulting image using an automatic global thresholding method. Then, based on the reconstructed surface and given the inspection probe trajectory, adapted focal laws to inspect the interior of the component are computed and applied at every location of the probe to correct the effect of the surface. The capabilities of the proposed inspection technique are illustrated by various simulated and experimental results carried out in a water tank. Its advantages and drawbacks will be discussed.</div></div>","PeriodicalId":18868,"journal":{"name":"Ndt & E International","volume":"158 ","pages":"Article 103535"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this paper conducts an in-depth investigation of CIP, establishing an analytical model to efficiently calculate the conductivity invariance point and validating it through numerical simulation and experiments. Additionally, this paper finds that the CIP arises from the combined effects of electromagnetic field coupling interference in multilayer structures and the electromagnetic interaction of the alien material layer itself. When the alien material is within the conductivity invariance point, the two effects cancel each other out, demonstrating CIP.

Measurement of the thickness of oxide film is imperative to maintain the safety of nuclear plants. The evaluation of oxide film thickness in nuclear power plant applications frequently involves the use of eddy current testing (ECT), which requires a calibration phase during the measurement process. Inaccuracies occur when the object’s material differs from the calibration samples. To address this issue, this paper presents an innovative approach that combines stacked array coils with a support vector regression (SVR) model to increase the measurement precision. The stacked array sensor comprises multiple coils separated by insulation layers with thicknesses of a few tens of microns, which function as internal distance standards to calibrate the oxide film thickness. The SVR model is developed to calculate the thickness of the oxide film from the measurement by solving the regression problem. This method mitigates the influence of the material property. A three-dimensional numerical model is developed to calculate the signals for various material conductivities. The simulation data are employed to train the SVR model and assess the accuracy of the approach.

The assessment of such discontinuities can be difficult, whereby methods of optical analysis present a viable technique to evaluate structural behaviour. This work utilises thermoelastic stress analysis (TSA) as a method to rapidly identify strut discontinuities in lattice structures and assess the resultant alteration in load transfer pathways. TSA scans were performed on lattice tensile specimens under cyclic loading and calibrated using strain gauge rosettes, which were compared to numerical models obtained using the finite element (FE) method. Several lattice topologies were investigated with various tensile loading magnitudes to assess the applicability of the TSA method for several stress ranges and load transfer pathways. TSA was found to be an effective method for both qualitative and quantitative analyses of discontinuities in the lattice specimens, which agreed with the FE models. Furthermore, the TSA scans showed the change in load transfer pathways through stress redistribution, highlighting the evolution of critical lattice members and identifying potential failure sites. This approach of rapid stress assessment can be applied to the design and in situ failure analysis of lightweight aerospace and spacecraft structures under dynamic loading conditions.</div></div>","PeriodicalId":18868,"journal":{"name":"Ndt & E International","volume":"158 ","pages":"Article 103587"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shear-horizontal (SH) waves generated by electromagnetic acoustic transducers (EMATs) have previously been shown to interact with both types of defect, with the reflection properties dependent on the defect geometry and the wavelength and wavemode chosen. This paper investigates the behaviour of the mode converted reflections that occur when an incident SH0 wave interacts with a defect in a plate. The properties of the reflected mode converted fundamental symmetric Lamb wave, S0, are shown to depend on the defect width, length and depth, which determine the angle at which a peak reflection occurs. This paper aims to develop fundamental understanding of the behaviour, showing that the defect width reflection behaviour follows a modified single-slit-diffraction behaviour, while the defect length dependence is due to interference between waves reflected from the front and back faces of the defect. Finite element simulations are primarily used, and verified experimentally. The S0 reflection is small, but results could be combined with analysis of SH0 reflections, enabling a higher probability of detection for small (mm-sized) defects.</div></div>","PeriodicalId":18868,"journal":{"name":"Ndt & E International","volume":"158 ","pages":"Article 103534"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145107541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, an embeddable multi-channel all-optical-fiber acousto-ultrasonic (AOF-AU) system is proposed. A pulsed laser was coupled into specialty optical fibers, and ultrasonic-guided waves were generated from photo-thermal-acoustic conversion. After propagating through the target structure, the ultrasonic wave was detected using a fiber Bragg grating (FBG), which was demodulated using the edge-filtering principle. The control section paired the channel in the optical switch and FBG array and synchronized the ultrasonic excitation and detection to achieve multi-channel SHM. A high-quality carbon fiber reinforced polymer (CFRP) embedded with optical fibers was manufactured; however, a flame-shaped ablation area was observed at the end of the specialty optical fiber. The cross-section of the CFRP did not exhibit a resin-rich area or fiber waviness. The correlation between the characteristics of the optical pulse signal and the ultrasonic wave was clarified under different parameters of the pulsed laser. The ultrasonic signal showed barely changed during continuous monitoring, demonstrating that damage does not accumulate further. In the multi-channel AOF-AU system, the multi-channel capability and strong directionality were demonstrated. In addition, the different attenuations of the ultrasonic waves evaluated in the AOF-AU system enabled easy localization of a hole within the CFRP laminate, demonstrating the capability of the newly proposed system for ultrasonic SHM.</div></div>","PeriodicalId":18868,"journal":{"name":"Ndt & E International","volume":"158 ","pages":"Article 103550"},"PeriodicalIF":4.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145107544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
